Contact the airlines, and see if any of them will donate a RT flight in the continental US to a hot spot for climbing... Vegas (Red Rocks,) El Paso (Hueco Tanks,) etc.

Great, just great.....THe Airlines are already in the toilet and you want them to forego price gouging and bait and switch tactics to seem benevolent when they need to be getting the most they can for them butts in them seats.... (an uninterested non airline stock holder...)

It's funny...all the comps I've been to have given such different prizes, depending on how good business was around the time of the comp. The best thing I've gotten has been a harness from a comp in Durango. Though occasionally prizes have made no sense- I had a friend get first in intermediate, and won a pair of Moccasyms. I got second in advanced and what do I get? A kaleidoscope that seemed to be made out of a paper towel roll. Fun stuff.

gift certificates to a place that sells a variety of gear (including clothing) is always nice. maybe some climbing vids. food always is good, too. gift certificates for cds, maybe...

one thing that is pretty cool is getting prizes from companies that normally lack distribution in your area, especially on items like shoes. i scored some saltics a while back that way and much prefered getting those instead of every other pair i can try on at the store down the street. just be sure and get a certificate and let them order the shoes themselves. i ended up with a kids size 6 or something tiny and had to ship them back for an exchange.

..cash is good. One thing I know means a lot...a cool trophy...not a left over baseball trophy that will be substituted for a climbing trophy, but something made just for boldering or climbing...along with cash!! :D

Good Luck with the comp, hope you get a great turnout. Hope to see you there with a big crew from DC.
